[单项选择]The growth of population during the past few centuries is no proof that population will continue to grow straight upward toward infinity and doom. On the contrary, demographic history offers evidence that population growth has not been at all constant. According to paleo-ecologist Edward Deevey, the past million years show three momentous changes. The first, a rapid increase in population around one million B, C, followed the innovations of tool-making and tool-using. But when the new power from the use of tools had been exploited, the rate of world population growth fell and became almost stable.
The next rapid jump in population started perhaps 10,000 years ago, when men began to keep herds, plow and plant the earth. Once again when initial productivity gains had been absorbed, the rate of population growth abated.
These two episodes suggest that the third great change, the present rapid growth, which began in the West between 250 and 350 years ago, may also slow down

[简答题]During the past few weeks, newspapers on both sides of the Atlantic have revealed in breathless terms the latest plan to invade Iraq.
They have described massive thrusts by armour from all sides; airborne attacks to take out Baghdad; vast seaborne raids. Saddam Hussein, according to one version, will be removed by dissidents inserted into Iraq backed by US Special Forces. Alternatively, Saddam will be taken out in a precision strike.
Civilian officials in the Bush administration have huffed and puffed about the "leaks", to the amusement of the intelligence and military professionals. "One thing you can say with an awful lot of certainty," one told The Observer newspaper in London last week, "is that there is going to be an awful lot of deception going on over the next few months."
